我们研究了全局色调映射算子(GTMO)，它在各种真实的HDR环境中转换物理刺激(即，亮度对比度(CR)高达大约)。105：1)通过将真实场景与复制的摄影图像进行实际比较而得到归一化视觉感知(NVP)。主观测试结果表明，我们提出的方法成功地将再现的图像转换成SDR(即，CR约为。102：1)。我们还证明了这些记录在SDR图像中的NVP可以被重新转换为LDR图像(即，CR约为。10：1)同时保持自然色调。
We investigate global tone mapping operators (GTMOs) that convert physical stimuli in various real HDR environments (i.e., luminance contrast ratio (CR) is up to approx. 105:1) into normalized visual percept (NVP) by actually comparing real scenes with reproduced photographic images. Subjective test results suggest that the images reproduced by our proposed method are successfully converted into SDR (i.e., CR is approx. 102:1). We also demonstrate that these NVPs recorded in SDR images can be re‐converted into LDR images (i.e., CR is approx. 10:1) while preserving natural tone.
